ROLLER-SKAT E.

SPECIFICATION forming part of Letters Patent No. 284,009, dated August28, 1883.

I Application filed January 26, 1883. (No model.)

Be it known that I, JOHN J OSEPH HENRY, of the city of Baltimore andState of Maryland, have invented certain Improvements in Roller-Skates,of which the following is a specification.

To fully understand the nature of my invention it must be borne in mindthat many per sons, especially children, learn to skate on floors ofbuildings and pavements with rollerskates, and while they may beproficient in this description of skating, they are totally unable toskate on ice with runner-skates, in view of the difficulty ofmaintaining an upright position.

The object of my invention is, therefore, the production of a skatewhich embodies the steadying properties of the roller type, and at thesame time is provided with an edge to slightly cut the ice, and therebyprevent dangerous lateral movement, which would be experienced in theuse of roller-skates having smooth rollers only. With this view Iprovide the rollers with one or more cuttingflanges, which projectslightly beyond their peripheries, as hereinafter more fully described.

In the accompanying drawings, forming a part hereof, Figure I is asideView of my improved skate. Fig. II is a front View of the same. Fig. IIIis a longitudinal section of one of the rollers. fied construction ofthe roller.

Similar letters of reference indicate similar parts 'in all the views.

A is the body of the skate, having the usual straps, a, and B B are therollers, held to the body in the usual manner. The rollers B consist ofcylindrical blocks 1), of wood, rubber, or other suitable material, inone or more parts, and a circular flange, c, of iron or steel, the edgeof which projects beyond the circumference of the roller. The flange maybe ground hollow, as shown in the drawings, or flat, as may be desired.

In Fig. IV the rolleris shown as provided with two flanges; but I do notlimit myself to any number. It will be understood that the flange orflanges cut into the ice to some extent and prevent lateral movement ofthe skate, while the body of the roller assists the wearer inmaintaining an erect position.

I claim as my invention In a roller-skate, the rollers thereof providedwith one or more metallic flanges projecting beyond their circumference,substantially as and for the purpose specified.
